On 22 July 2014, Dioudis made a transfer to Belgian giant Club Brugge on a two-years' contract, with an option for an additional season.

[7] On 25 July 2017, after only a year with Aris, the talented Greek goalkeeper will most likely continue his career at Panathinaikos, since the two clubs agreed terms.

The Greens will pay an estimated amount of €150,000 in order to complete the purchase of 24-year-old international, who is expected to sign three-season contract with manager Marinos Ouzounidis' team and replace experienced Englishman Luke Steele.

On 11 November 2018, Dioudis in a 1–1 away derby with rivals Olympiacos suffered a face injury in a strong aerial challenge from Bibras Natcho.

The Israeli midfielder earned a yellow card and Panathinaikos were forced to replace the injured Dioudis with Konstantinos Kotsaris.

Dioudis played at the same high level throughout the entire regular season, recording an impressive total of 11 clean sheets while conceding 22 goals in 25 games.

The most important matches in his international career are the semi-final and final of 2012 UEFA European Under-19 Football Championship, against England and Spain, making very good appearances.
